Abstract
A novel biodegradable, water-resistant polymer material which can be produced with defined material properties is suggested, in particular in the form of foils, films, strips, masses, molded articles or the like, this material consisting essentially of a product of the cross-linking reaction of polysaccharides and/or polypeptides, the hydroxyl, amino, imino, thiol and/or carboxyl groups of which are derivatized at least partially in a non-radical reaction with agents which include groups cross-linkable in a process step following the derivatization and separate therefrom.
